I was wondering if someone could help me with these compression test numbers.

The car the test was done on is an RX8 2008 Series 1, the test was done at 55,000 K's, the car now has 67,000 K's i am looking at buying this car and need help translating the compression test numbers and what they ultimately mean.

Whether or not they are good numbers is a matter of opinion and how much you expect to get out of the engine. They are well within Mazda's specs, but indicates an engine that has experienced some wear. Check out this post from rx8club.com, which suggests these numbers should attract some caution, but keep in mind that is just one person's opinion: https://www.rx8club.com/new-member-foru ... ost4533734 For me that opinion and the chart is pretty pessimistic - if it lasts 40,000km that might be perfectly fine in your mind. Depends on how many km's you plan on driving and the price.

Like mazrx5 said in the other thread, all these engines will eventually require a rebuild. So factor in the potential of that accordingly. It's the same as looking at buying import FDs.

Consider a series 2 if the cash extends that far. The oil injection system is improved, so they should last much longer between rebuilds. In theory.

An average RX8 engine rebuild will cost approx $9k, from calling a couple places. Pretty sure most shops will demand two new housings, plus whatever else is needed.

I'm in the midst of rebuilding a series 1 RX8 engine at the moment and even without paying a shop it's expensive. The parts cost adds up quick. It didn't look good inside (around 170000 on the chassis, but I assume it had been rebuilt at least once before or was a remanufacture or something, no way the original engine went that far). By the way my RX8 was about $3k with a known dead engine, and the car was is good condition, not great, but pretty good. If you get lucky and can something that is known dead for about $5k in great condition, just needing a rebuild that'd be perfect.
